formats & front panel pots -- Re: [SynthModules] ...

2004-04-09 by Mike Marsh

A couple of thoughts, all of which I've implemented because I don't 
like the 1/8" format:

* Stooge Larry will make you 1/8" to 1/4" cables.  His cables and 
connectors are wonderful.  This is an optimal soultion. (Truth be 
told, I don't have any of these yet, but I will when he does the next 
cable run).

* John Blacet has a $12.00 frame that adapts Frac modules to MOTM 
size.  The frame also includes pilot holes for 8 x 1/4" jacks: you 
wire these from the module's existing 1/8" jacks.  I did this for my 
Noise Ring and it works very well.  You have either 1/8" or 1/4" 
jacks available as needed.  Note that for the Noise Ring a little 
shaving was needed to get the pots to fit behind the frame.  Also the 
frame is just slightly too wide, but can be shaved with a little 
Dremel action.

* Paul Schreiber has an adpater panel in MOTM format that includes 8 
each of 1/4", 1/8", and Banana jacks.

* Stooge panels rock.  I've converted several Blacet modules to MOTM 
and though it takes a little DIY skill, the end results are 
terrific.  NOTHING cooler than an MOTM-ized Time Machine!

* Finally, Schaeffer will create a nice panel for you of your own 
design. A 1U MOTM panel could probably fit 12 1/4" and 12 1/8" if you 
want to roll your own adapter panel.
